Included in this lot we have a Pennzoil United Inc. porcelain enamel advertising sign. The sign displays steel construction with a porcelain enamel coating. The piece displays a yellow base with a black border. The sign is marked across the face reading "Pennzoil United, Inc. Leo Tank Battery SW1/4 SE1/4 SEC.4 - T23N - R59 E Richland Co., Mont.". The top of the sign shows the Pennzoil bell logo. This one sided sign shows wall mounting holes in each corner. The sign shows good condition overall with some light wear across the perimeter. It measures 20" wide by 14" tall.
